At least not in my opinion. My buddy did the same thing when we were in high school about 6 or 7 years ago. Booted up in Linux, copied the SAM file over, cracked it at home. Did it a few times until we found one that the administrator account had logged into. He was never caught until the end of the year because we decided to pull a prank and change the standard wallpaper for all the student accounts to this http://img689.imageshack.us/img689/7629/gib.png. He was caught because as it turns out, the system was setup to capture screenshots of anyone logged in every 10 seconds, combined with the fact that he signed in to the library to use the computer, they were able to catch him. I don't think they ever found out about changing some grades, but I'm not sure about that.

I actually bought both Machinarium and World of Goo. Good games, kinda makes me sad to read this article though.

I would also argue that PS3 using BluRay for their games would have an impact on that as well, even if the encryption were broken. Speaking on behalf of myself anyways, burning dvds would be far cheaper and more convenient.

Don't forget built in USB port, card reader, on board hard drive for tivo, network access for streaming, and an RF remote so I can walk out of the room and change tracks if I need to. Did I miss anything?
